Question 1

Rust on arches, doors and sills (Sprinter 906)

Accepted Answer

The Sprinter 906 is well known for rust on the wheel arches, door bottoms, sills, windscreen frame and rear step, as well as on the chassis rails. Corrosion can cause MOT failures and expensive bodywork.

Question 2

Clogged EGR valve (2.1 CDI)

Accepted Answer

Carbon build-up in the EGR valve and inlet manifold on the 2.1 CDI causes hesitation, rough idle, black smoke, an engine management light and limp mode. It is made worse by short journeys and long periods of idling.

Question 3

Leaking injector seals (2.1 CDI)

Accepted Answer

Failed injector copper washers let combustion gases escape, producing a chuffing noise, a smell of diesel fumes in the cabin and black carbon deposits ('black death') around the injectors. Left alone, the injectors seize in the head and become very hard to remove.
